CVE-2023-30535Network attack vector

Code execution via unvalidated SSO URL

Published Apr 14, 2023 · Updated Feb 6, 2025

Command injection in Snowflake JDBC Driver before 3.13.29 allows remote attackers to execute code through a crafted SSO URL. SessionUtilExternalBrowser.openBrowser passes the server-supplied URL to Desktop.browse without restricting its scheme, allowing a file URL to invoke a local handler. Exploitation requires a malicious server response and user interaction with its crafted connection URL; successful execution runs on the user's machine.
